NOAH HARRIS, OF VINCENNES', INDINA COFFEE-R'OASTER.

SPEGIFICATION forming part of Letters'Patent No. 256,139, dated April 11, 1882.

v I Application filed October 20, 1880. Rcnewcd January 9, 1882. (No model.)

To all 'w/Lom z't may conccrn Be it known that I, Noni-1 HARmsacitien of the United States, residing at Vineennes, in the county ofKnox and State ofIndiana, have invented certain new and useful Im provem ents in Ootfee-Roasters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being` had to the accompanying drawings, and to letters or .figures of reference marked thereon,lwhich form a part of this speciiication.

The present invention relates to improvements in cylinder cofi'ee-roasters, and its object is to provide simple and effective means for closing and handling the cylinder and iuspecting its contents.

The invention consists essentially in ay combined door or cap plate and window, which is so constructed and arranged in respect to a central opening formed in the cylinder-head that the coffee can be 'roasted in an expeditiousl manner without incurring theliability of smoking the window.

The invention also consists in other details of construction and arrangement, which will beA hereinafter more fully described, and then set forth. in the clainis.

Figurel is a perspective view ofa Coffee-master seated o n a stove. Fig. 2 is a longitudinal section of the cylinder` and supporting devices. Fig. 3 is an innerface view ofthe cap orcover; and Fig. 4 is a detailed view of the apertured cylinder-head having notches and interior inclined surfaces en gagin g with studs on the cover.

The cylindercoffee-receiver is generally const'ructed of a Sheet-metal body or cylinder, A, and two solid cast-metal end heads, B O, and is provided with internal ribs or wings, D, for agitating` the cofl'ee as the cylinder is revolved. A circular opening, E, is formed in the central portion of the head B, the edge of said openin g having notches a', as is shown in Fig. 4. Into this opening there is fitted a door or cap consisting of two cireular metallic plates,-I` and G, and a window or sheet of mica, M, interposed betweensaid plates. The inner plate,F, which is made sornewhat smaller than the outer plate, Gr, is provided with peripheral lugs or projections b, ,corresponding in number with the notchesa in the head. Adj acentto the notches are formed inclined surfaces az, the object of which is to cause the lugs on the cover, as they glide over the same, to draw the cover into the .side of the plate F. As an auxiliary fastening medium the plate G is provided with studs or pins d, which enter openings in the plate F. It is evident that by fitting the door or cap into the opening` in the cylinder-head so that the lugs b and notches a' register with each other, and then partially rotating said (lo'or or' cap, the same is retained in position Without the aid of other fastcning devices. The rod H is made quite long, and has its end formed into a hand-crank, which is provided with a non-conducting handle,f.

The head O of the cylinder is provided with an axis or spindle, I, formed of a short rod having an outer loop or ring, J, this rod being secured to the end head by riveting it on the inner side thereof.

The cylinder or drum, when in use for roasting coffee, is monntedor journaled in notched nprights K of a ring-shaped Steve-plate, -L. This plate fits into the stove-hole, and is suitably apertured to permit the roasting cylinder or drum. to be passed sufticiently deep into the fire to quickly heat the drum. The plate L is provided with risers Z and seats l', of different sizesto fit the apertures ofdifferent-sized stoves.

The rods H and I form the axis of the drum and rest in the notched upper ends of the uprights K. i

The operation is as follows, viz: The cap or door` is removed and the cylinder filled with coffee. Then the door is replaced and the cylinder mounted in the stove-plate over a fire. By rotatin g the drum through the medium of rod Hthecoffeeis thoroughly agitated and roasted in an expeditious manner, the window or windows in the center of the end head providing' easy and never-failng means ofinspecting the contents' of the cylinder or watching the progress of the roasting operation. The position of the windows is very important, because if they were arranged near the periphery of the drum they would become smoked, th us destroyingtheirtransparency and rendering them useless for 'theirintended purpose. After the coffee has been sufticiently roasted a rod or stick is passed through the loop J of the rod I for lifting the drum ofi' the fire. Then by removing' the door or Cap by slightly turning the same the contents ofthe drum can easily be discharged.

Having thus descrihed my invention, what I claim as new, and desire to secure by Letters Patent, is

In testiinony whereof I aftix my signaturein 35 presenee of two witnesses.
